CS01 - C# OO Primer - 1 Day
Course Description
This course is designed to provide the developer with a broad overview of the C# object oriented approach. Developers will learn the key elements of object oriented applications including classes, interfaces, attributes, objects, access levels, inheritance and polymorphism.
Although this course does not instruct the developer on full detailed object oriented design techniques, on completion of this course, developers will be ready to move on to more detailed C# training courses in a 'non-design' capacity.
Pre-requisites
None.
Objectives
Whilst covering the basics of C# object oriented programming concepts, this course also aims to give an insight into objects, classes and messaging.
Issues such as encapsulation, inheritance, polymorphism, object modelling and the Unified Modelling Language are discussed.
On completion of this course the student will be able to:
- Understand the concepts of object oriented programming
- Understand and differentiate between objects and classes
- Understand object instantiation
- Understand and differentiate between instance methods and variables and class methods and variables
- Understand the concept and benefits of messaging
- Understand the concept and benefits of encapsulation
- Understand the concept and benefits of inheritance
- Understand the concept and benefits of interfaces
- Understand the concept and benefits of polymorphism
- Understand the concept of object modelling and the Unified Modelling Language
Environment
Lecture based.
Customisation
For on-site courses (i.e. at your premises), we are more than happy to tailor the course agenda to suit your exact requirements. In many cases, we are able to build your in-house standards and naming conventions into the delivered course.
